Fertility apps can help people track their ovulation cycles to understand when they are likely to be fertile. People can use fertility apps when trying to conceive.

A quick look at the 11 best fertility tracking and planning apps:

The majority of fertility apps calculate fertile windows using menstrual cycle data. Some apps come with devices for measuring body temperature or analyzing urine samples.

For example, some fertility apps track basal body temperature (BBT), which rises after ovulation, using input data or direct temperature reading from linked smart devices.

Other apps come with devices to take and analyze urine samples to measure luteinizing hormone (LH) or progesterone levels.

An LH rise can indicate active ovulation.

Progesterone rises after ovulation, which also increases BBT. Any method measuring progesterone BBT can confirm that ovulation happened, but may not identify peak fertile window as it occurs, unlike methods that track LH levels.

These two hormones rise in level when ovulation occurs, indicating a fertile window. A progesterone rise triggers ovulation,

People with polycystic ovary syndrome (PCOS) or irregular menstrual cycles may not experience typical fluctuation in

According to a 2021 study, fertility apps are unregulated. Further research is necessary to confirm their accuracy for planning or avoiding conception.

Best for accurate results: Mira

Available on: Apple Store and Google Play

Price: Mira Plus Starter kit costs $199 upfront or 4 interest-free installments of $49.75.

Features:

  • predicts 6-day fertility window and ovulation day
  • 99% lab-grade accuracy
  • FDA compliant
  • 24/7 customer support
  • free app for hormone charts and insights
  • using hormone tracking and urine tests, ovulation and fertility days are more accurate than purely app-based fertility trackers
  • personalized fertility tips
  • noninvasive
  • PCOS friendly

How it works: This app works alongside a fertility tracking kit that users must purchase. The kit includes devices such as the fertility analyzer and fertility ‘wands’.

A user takes a urine sample and, using a fertility wand, dips it into the sample for ten seconds. Mira recommends the first urination in the morning for best results. The user then inserts the wand into the analyzer. Results are available within 16 minutes. The analyzer then connects to the app to provide a fertility window and personalized information.

The use of hormone tracking makes this app accurate as progesterone is one of the main hormones present during the luteal phase. Rising progesterone levels show the user may have successfully ovulated.

This app may suit people with PCOS or other conditions affecting menstrual cycles, as it uses urine tests to accurately track hormone levels. People with PCOS may have irregular hormone levels and menstrual cycles, making manual forms of fertility tracking, such as using a calendar, less reliable.

A person should take into consideration financial expectations when choosing a fertility app. This ensures it is within a person’s price range.

If a person comfortable using technology or reading scientific data may prefer an app that uses graphs could be beneficial. However, if a person prefers an easier layout, they should seek a simpler app.

An app that allows for input of additional measurements, such as BBT or hormone levels, can provide a more accurate prediction of fertility windows. For example, if an app assesses body temperature or measures hormones, it can provide a more accurate prediction on ovulation and fertility days.

A 2021 study has found that fertility apps generally do not support users across different stages of life. Fertility apps are usually designed to support conception during reproductive years, but lack the flexibility to adapt to users’ changing needs and life goals.

The following are common questions and answers about fertility apps:

Which fertility app is most accurate?

On our list above, Mira may provide the most comprehensive data due to using urine samples. It tracks urine LH and progesterone levels, which may provide evidence of ovulation.

Apps that track BBT are also useful for indicating ovulation. Ovusense uses a smart device to sync BBT data with the app.

A person should thoroughly research and speak to a healthcare professional before purchasing an app.

Is there an app to help a person get pregnant?

Fertility apps estimate fertility windows, which can help people to conceive. However, there is not an app that can guarantee a pregnancy.

A person should speak to a doctor for information on conceiving if they are experiencing difficulties. An app can be a useful guide, but a doctor can offer personalized advice.

How accurate are fertility apps?

This is dependent on the app and the person using them. Apps that use thermometers or urine tests are more accurate.

If an app relies solely on data inputted from a user, this could be less accurate as a user can make mistakes or may not have access to all the information needed for a better estimate on fertility windows.

If a person has irregular periods or has been diagnosed with PCOS, it may be more difficult for an app to accurately predict ovulation days, even with the use of measuring devices.

A 2018 study found that the accuracy of ovulation estimation based on data-provided menstrual cycle apps, without the use of medical devices for measuring hormone levels, was generally no higher than 21%.

Fertility apps are a useful tool to help identify fertile periods. They can provide estimates on ovulation days and fertility windows.

Some rely on data input from a user, while others use measurements and tests connected to the apps, such as thermometers and urine tests, to improve accuracy. Fertility apps cannot be 100% accurate.

People should speak to a doctor for advice on fertility issues. Apps are useful for general guidance but should not replace professional medical advice.
